Letters Patent No. 93,289, dated August 3, 1869.

IMPROVED CARRIAGE-JACK.

The Schedule referred to in these Letters Patent and making part of the same.

and applied to use, a certain new and useful Improvement in Carriage-Jacks; and we do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure l is a side view of said jack;

Figure 2 is an elevation endwise-of the lever; and

Figure 3 is a partial side view of the jack, with the lever in a lower position;

Similar marks of referencc'denote the same parts.

This invention relates to a' carriage-jack, that is constructed so as to be adapted to diiferent heights of axles, and so that it can be folded into a s1n'allcompass, the raising and lowering of the axle being affected by a lever, to which is hinged a ratchet-sector, taking a tooth or pawl-plate, and an oscillating hearing, with an elastic surface, is provided, receiving the axle, so as to take an even bearing upon said axle, and not to injure the surface.

In the drawing a and b are the legs, between which is the lever c, and d is a pin, passing through. the three, and forming ,the fulcrum for the lever c, and uniting the legs, so

that all three may be folded up togetherinto a small compass, or be spread, as infig. 1', for use.

The bolt or pin (1 also passes through the side-pieces e of the pawl-plate f, and from this plate f a slotted link, g, extends toa pin, 2, on the leg I), and this slotted link 9 has notches to set over the pin 2, so that the legs a. and I) can be spread more or less, and held in position.

To the under side of the lever c the ratchet-sector his hinged, at 3, and extends along beloiv the lever 0, so that the teeth thereof take the pawl-plate f; but the same can be raised off said pawl-plate by-a lever-extension, it, from said sector It, either formed as part of said sector, or hinged thereto, as at 5, and sliding upon a screw or pin, 6, on the under side of the lever c, aslot being provided in It, at this point. We prefer, and have shown in the drawing, this lastnanicd cmistructiou.

ltwill now be understood that the lc'ver'c is to be employed for lifting the carriage, and that the ratchetsector it keeps the same elevated, and that when the carriage or vehicle is to be lowered, the ratchet-sector is relieved of strain, and drawn back from the plate f, by the lever lc, is the lever c as moved to lower the carriage-axle. I v

The bolt cl can be drawn out, and either or both legs a b moved endwise along, and the bolt d re-entered in another hole, so as to lower or raise the ful-,

0mm (1, lever c, and parts connected therewith, bodily.

In fig. 3 the jack isrcprescnted as partially lowered, by the bolt (Z being entered'into, a lower hole in the le b.

Upon the end of the lever c is the oscillating hearing m, upon a pivot, 16, that is formed bya downward projection on the under side of the bearing m, entering a mortise in o, and held by a pin. This bearing accommodates itself to the under surface of the axle, as the lever is swung; and, in order to prevent injury to the painted surface of the axle, or other part of the vehicle, we introduce a block of- India rubber, 12, form-.

ing the upper surface of said hearing.

The link might be connected, at one end, to a pin or projection from the leg a, instead of the pawl-plate f, and the pin or leg I) may be movable, or a second one provided.

The legs a and I) might be fastened together, and

used with a footor legs to swingfrom them. and the holes for the pin or bolt d might open into the side-of a mortise, running lengthwise of the legs a and b, so as not to have to draw out said bolt in changing it.

What we claim, and desire to secure by Letters Patent, is

1'. The ratchet-scctor h, lever k, and pawl-plate f, in combination with the lever c ofthe carriage-jack, substantially as and for the purposes set forth.

2., In combination with the foregoing, the link g, legs a and b, andvbolt d, as and for the purposes set forth.

3. The India-rubber bearing-surface -n, combined with'the lever of a carriage-jack, as and for the purposes set forth.

In witnesswhereof, we have hereunto set our signatures, this 6th day of March, A. D. 1869.

D. ELLIOT.
